Ditto crack the throttle and get a new battery to make sure,And don't let the button go untill it starts..
The motor it still tight,put some miles on it..
When I had my 13-1 1397 it started right up even on hot days..
What do you have the cams set at?
I need to get in touch with you,and did you post any pics of your bike with the new paint yet?
